Study Notes
Introduction to Information Processing
- Information processing involves acquiring, recording, organizing, retrieving, displaying, and disseminating information.
- Timely, accurate, complete, and comprehensive information is crucial for effective processing.
- The Information Processing Cycle consists of input, processing, storage, and output stages.
- The Multi-Store Memory Model proposes three memory stores: sensory register, short-term memory (STM), and long-term memory (LTM).
- Sensory memory holds information perceived through the five senses.
- STM stores information for approximately 30 seconds.
- Working memory plays a role in cognitive processing of information in STM.
- Iconic memory (visual information) lasts for half a second while echoic memory (auditory information) lasts for 3 to 4 seconds.
- LTM has unlimited storage capacity and can retain memories for long periods.
- Methods for storing information in LTM include repetition, connecting information, and chunking.
- LTM comprises explicit (declarative) and implicit (procedural) memory. Semantic memory is a type of explicit memory that stores information.
- Information processing in libraries includes activities like managing online databases, circulation, and generating library reports and statistics.
Digital Revolution and Its Impact
- The Digital Revolution involves the shift from analog and mechanical technologies to digital technologies.
-
Advantages of the digital revolution for libraries include:
- Shift from traditional cataloging to digital cataloging (e.g., MARC)
- Open access initiatives
- Diverse learning formats
- Improved collection and storage
- Evolving staff roles and responsibilities
-
Disadvantages of the digital revolution for libraries include:
- Potential loss of content
- Increased dependence on technology
- Digital divide
- Concerns about credibility
- Decreased funding and support for libraries
Digital Convergence
- Digital convergence refers to the merging of media and technological features into a single device.
- Examples of technological convergence include mobile phones, smart TVs, and iPads, while media convergence includes books, television, radio, and social media platforms.
- Network convergence encompasses technologies like FaceTime and Skype.
- Libraries benefit from digital convergence through:
- Increased accessibility of information
- Enhanced dissemination of information
- Improved preservation of information
- Reduced expenses
- Wider reach to various stakeholders
Digital Devices and Representation
- Digital devices receive, process, and send digital information (e.g., mobile phones, tablets, laptops).
- Digital representation involves transforming various data types (text, images, music, video) into binary code (1s and 0s) for efficient storage and transfer.
- Digital processing entails transforming raw data into usable information.
Computer Hardware
- A personal computer system comprises various components working together.
- RAM (Random Access Memory) is the main memory of a computer system, playing a crucial role in data access and processing.
Input and Output Devices
- Input devices allow users to feed data or instructions into a computer system.
- Common input devices include:
- Keyboard: for typing letters, numbers, and symbols
- Mouse: for controlling the cursor on the screen
- Joystick: for controlling cursor movement
- Light Pen: for interacting with the display screen
- Biometrics (Fingerprint Scanner): for authentication and security
- Scanner: for digitizing images or documents
- Graphic Tablet: for drawing and graphic creation
- Microphone: for recording sound
- Magnetic Ink Card Reader (MICR): for processing bank checks
- Optical Character Reader (OCR): for reading printed text
- Bar Code Reader: for reading bar codes
- Optical Mark Reader (OMR): for recognizing marks on forms
- Display devices present information visually.
- Types of display devices include:
- Cathode Ray Tubes (CRT) Monitors
- Liquid Crystal Display (LCD)
- LED/OLED (Light Emitting Diode Display)
- Ultrawide Monitor
- Touchscreen Monitors
- Curved Monitors
- Printers produce hard copies of text and images.
- Types of printers: Inkjet Printers, Laser Printers
Software Categories and Acquisition

System Software manages and controls computer hardware
- Operating System (OS): responsible for overall hardware management and operation.
- Device Driver: enables communication between OS and hardware devices.
- Firmware: in-built software that instructs hardware devices.
- Utilities: tools that enhance OS functions and system performance.
-
Application Software performs specific tasks for users.
- Common application software includes:
- Word Processor: for creating and editing text documents
- Graphic Software: for image creation and editing
- Spreadsheet Software: for data storage, manipulation, and analysis
- Presentation Software: for creating visual presentations
- Web Browser: for accessing and viewing information on the internet
- Productivity Software: for various tasks such as document creation, presentation development, and multimedia editing
- Educational Software: for supporting students' learning
- Open-Source Software: freely available software with open source code
- Closed Source Software (Proprietary Software): owned and distributed by a specific company or organization.
- Common application software includes:
-
Software Acquisition Process:
- Needs Assessment
- Market Research
- Request for Proposal (RFP)
- Proposal Evaluation
- Vendor Selection
- Contract Negotiation
